Figures and Shapes

Northern Computer Lab

Arc - A portion of the circumference of a circle. 

Base - The bottom line of a shape

Circle - A simple shape made up of all the points on a plane that are the same distance from a single point. 

Closed figure - Any figure that has the same start and end point is a closed figure. 

Cone - A three dimensional object that has a flat circular base that tapers to a single point. 

Cube - A cube is a three dimensional object bound by six identical squares.

 

Cylinder - A cylinder is a three dimensional object with two parallel bases (which are usually circles) connected by a curved surface. 

Equiangular - When all angles inside a polygon are the same, it is said to be equiangular. A square and an equilateral triangle are equiangular. 

Face - One side or plane of a three dimensional object. 

 

. 

Open figure - A two-dimensional object that is not closed. 

Parallelogram - A quadrilateral with two sets of parallel sides. Opposite sides are the same length and opposite angles are equal in a parallelogram.

. 

Polygon - A closed figure made up of straight lines.

Polyhedron - A three-dimensional object composed of flat faces and straight lines. 

Prism - A three-dimensional object with ends that are parallel and congruent as well as sides that are parallelograms. 

Rectangle - A quadrilateral, or four sided polygon, with four right angles

Rhombus - A rhombus is a parallelogram where all four sides are the same length. 

Sphere - A three-dimensional object where every point is the same distance from the center. A basketball is a sphere. 

Square - A rectangle where all four sides are the same length. 

. 

Trapezoid - A quadrilateral with only one pair of parallel sides.
